Sequencing Logic
605C Frequency Inverter
Communications Status
The COMMS STATUS parameter (Tag 272) in the COMMS CONTROL function block
monitors the sequencing of the Inverter. It is a 16-bit word based on standard fieldbus drive
profiles. Some bits are not implemented in the initial release and are set to 0 (see “Supported”
column of the table below).
Bit Name Description Supported
0 Ready To Switch On √
1 Switched On Ready for operation (refer control bit 0) √
2 Operation Enabled (refer control bit 3) √
3 Fault Tripped √
4 (Not) Voltage Disabled OFF 2 Command pending √
5 (Not) Quick Stop OFF 3 Command pending √
6 Switch On Disable Switch On Inhibited √

Ready To Switch On
Same as the SWITCH ON ENABLE output parameter of the SEQUENCING LOGIC function
block.
Switched On
Same as the SWITCHED ON output parameter of the SEQUENCING LOGIC function block.
Operation Enabled
Same as the RUNNING output parameter of the SEQUENCING LOGIC function block.
Fault
Same as the TRIPPED output parameter of the SEQUENCING LOGIC function block.
(Not) Voltage Disabled
If in REMOTE COMMS mode, this is the same as Bit 1 of the COMMS COMMAND
parameter. Otherwise it is the same as the /COAST STOP input parameter of the
SEQUENCING LOGIC function block.
(Not) Quick Stop
If in REMOTE COMMS mode, this is the same as Bit 2 of the COMMS COMMAND
parameter. Otherwise it is the same as the /FAST STOP input parameter of the SEQUENCING
LOGIC function block.
Switch On Disable
Set (=1) only when in START DISABLED state.
Remote
This bit is set (= 1) if the Inverter is in Remote mode AND the parameter REMOTE COMMS
SEL of the COMMS CONTROL function block is Set (= 1).
